ENGINE-FRAME.

SPECIFICATION forming part of Letters Patent No. 396,209, dated January15, 1889. Application filed February 20, 1888. $eria1No. 264,607. (Nomodel.)

To all whom it may concern.-

Be it known that I, ALBERT L. Inn, of Spring field, in the county ofSangamon and State of Illinois, have invented certain new and usefulImprovements in Engine-Frames; and I do hereby declare that thefollowing is afull, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in steam, gas, and otherengine-frames, and more particularly to frames for horizontal stationaryengines of that class in which the frame is continuous and supports thecylinder at one end and is provided with crank-shaft bearings at itsopposite end.

The invention consists in the matters hereinafter described, and pointedout in the .ap-

pended claims.

I11 the accompanying drawings, Figure 1 is a perspective view of anengine and frame embodying my invention. Fig. 2 is a plan view of theframe. Fig. 3 is a longitudinal section of the engine-frame andoperative parts therein. Fig. l is a cross-section of the engine-frame,taken upon line 4 4: of Fig. 3. Fig. 5 is a horizontal section of theframe, taken upon line 5 5 of Fig. 3. Fig. 6 is a detail cross-sectionof the frame, taken upon line 6 6 of Fig. 3.

As illustrated in said drawings, A the engine-cylinder.

B is the frame; the crank-shaft; D, the piston-rod; E, the cross-head,and G.the connecting-rod. The crank-shaft is shown in the drawings asprovided with two crank-disks, C C, to which is attached a crank-pin, Cengaging the connecting-rod G.

C is a fly-wheel upon the crankshaft.

The cross-head E illustrated is like that shown in a prior patent, No.321,72, dated July 7, 1885, and consists of a main part, E, of hollow orbox form, and two bearingplates, E Ei secured to the top and bottom ofthe part E and engaging the cross-head guides F F of the frame.

E is a wrist-pin, which is secured in the opposite side Walls of thehollow part E of the cross-head and is engaged with the connecting-rodG.

The engine-frame is constructed as follows: Said frame is provided withabase, B, which is cast hollow and comprises two side walls, 1) b, and atop wall, 5 which latter forms the support for the lower cross-headguide, F. Themain or upper part of the frame, in its part B adjacent tothe cross-head guides, is provided with two side walls, B B which connect said cross-head guides at both sides thereof, so as to give atubular form to said part B of the frame. The said walls B B desirablyform upward continuations of the side walls, 1) b, of the frame-base B.IVithin said hollow base are located cross ribs or flanges 19 bextending between the sidewalls, b b, of the base and serving to supportthe wall b and to give stiffness to the lower crosshead guide, F, formedupon said wall. The lower part of the base B terminates inoutwardlyextending horizontal flanges b b, which rest upon the enginebed or foundation and through which suitable bolts are in 'serted forholding the frame in place. Said .flanges extend the entire length ofthe frame from the cylinder to a point beneath the crank-shaft. At theend of the frame adjacent to the cylinder the tubular part B is extendedpast the base B, so as to forma cylindric extension, 12 to which thecylinder is attached, the frame in this respect being like that shownand described in a prior patent, N 0. 314,381, granted to me March 24,1885. Said cylindric part or extension b is herein shown as castintegral with the cylinder-head A, thereby rendering any separate headunnecessary.

The horizontal wall Z2 which forms the top wall of the hollow base 13and the bottom wall of the tubular part B is extended from the end ofthe lower cross-head guide to form a wall, 13*, which slopes downwardlyto a point beneath the crank-disks and extends to the end of the frame.Said wall B in its part adjacent to and beneath the crank-shaft islocated at the level of the bottom of the frame and joins at its sideand end margins with the external base-flange, 12 of the frame.

Each of the crank-shaft bearings Z) is supported by two inner and outervertical walls, 13 B, which form continuations of the side wall, B atthe same side of the tubular part 3 of the frame, and which are joinedat their upper margins and Together form a hollow girder practically inalignment with the said side wall, 13*. The said walls 1% 1% maybecurved inwardly or brought together at their upper margins; but asherein shown they are connected by a flat horizontal top plate or wall,If, which terminates in or is joined to the shalt-bearing h. At theirlower parts The inner and outer side walls, l3 13", extend downwardly toThe plate ll, which, at This point, forms the bottom of the frame. Theinner and outer walls, l3 l3", sustain the inner and outer parts of theerank-bearings, and term rigid and stitl girders, Tending To hold thecranlcbearings accurately in alignment with each other and to preventyielding ol; the said bearings under whatever strain may be put uponThem. The tubular main part 1:3 ot' the frame, connected at one enddirectly with the cylinder, in connection with The parallel hollowgirders formed by The walls ll BZand 'lj'orming eontimiatitms of saidtubular part, form a frame of great stiffness and strength, and onewhich is at the same Time. of relatively little weight and contains aminimun quantity of metal.

13 is a transverse end wall, which extends across the lower part olf Thel'rame exterior to the (wank-disks, and isconnecttal with the walls l313 by vertical side walls, 1 1;, the rear or end margins ol said walls 33" being, in the particular censtruetitni illustrated, sloped orinclined outwa rdly and downwardly from The shal't-lmtrings to thebottom of The frame. The walls l3" 13" are triangular in form and tillthe spaces between the side edges of the wall ll and the rear edges olThe walls 13 13 Said walls l3 l3 and the walls B and 13" ll, togetherwith The inclined wall 13, form a basin or tank, ll, which may beemployed to contain a quantity of oil or other lubricant for The purposeof lubricating the several parts of the engine in the manner set forthin a separate application, Serial No. 264:,609, liled by me in TheUnited States Patent Ot'lice siinultaneousl herewith.

ll is a hood or cover, which extends over the crank-disks and is tittedat its margins To the adjacent edges of the walls l3 ll B 13"]? and tothe adjacent edge I), Fig. 3, of the tubular part .13 of the frame. Saidhood or cover, in connection with The adjz'tcent parts of the framectmstructed as above set forth, serves to entirely inclose the saidcrank-disks and connected operative parts, and thereby protects The samefrom dust and dirt, and at the same time confines the oil or lubricantand prevents the same from escaping to the exterior of the frame orbeing Thrown outwardly upon surroumling obj eets.

In Vl6\\' ot' the advantages gained by the employment of such hood orcover in connection with a frame which is tubular near the cylinder, andis branched or forked to afford two bearings for the crank-shalt, aconst ruw tion of this kind herein claimed as new.

The construction illustrated, embracing the 7 frame and hood made asabove setforth, to gether with the cross-wall l ,t:'orini n g the lowerpart of a casing or housing surrounding the crank-disks, is also hereinspecifically claimed as a se iarate and further innn'ovement.

I is a reniovabledoor, which is placed in one of the side walls, ll, ofThe tubular part 3' of the frame To alt'ord access to The cross head andguides when necessary for repairs or other purposes.

I claim as my inventi n1.
